I run my own company and have a home office and a regular office, each with a mouse, keyboard, and big monitor. With my laptop I can just take it back and forth - all files come with me and the machine is in the exact state when I boot it up at home as when it was at the office. If I need to go out of town, I just take the laptop with me and I can do everything I would normally do, just with a smaller screen. At least for web development, speed usually isn't an issue ... putting in an SSD drive a year or so ago, though, was the best thing I did - very noticeable speed increase! So, for me it's a convenience factor.
